No.429,058 Claims priority, application Japan, May 18, 1964, 39/158,346 1Claim. (C1. 68-5) This invention relates to improvements in an apparatusfor continuously leading textiles into and out of a pressure-treatingchamber filled with a dyeing solution, bleaching solution, steam or anyother treating fluid to treat the textiles with such fluid.

An object of the present invention is to provide an apparatus of asimple construction for leading textiles in and out whereby it is madepossible to continuously lead textiles into and out of apressure-treating chamber in a substantially perfectly air-tight orliquid-tight state.

An embodiment of the present invention shall be explained with referenceto the accompanying drawings in which:

FIGURE 1 is a partly sectioned perspective view of an embodiment of thepresent invention;

FIGURE 2 is a vertically sectioned view of the same;

FIGURE 3 is a partly sectioned side view of the same;

FIGURE 4 is a perspective view of a part of the same;

FIGURE 5 is a vertically sectioned sketch of a pressure-treating chamberprovided with the apparatus of the present invention.

In the drawings, 1 is a feeding roll device consisting of two rolls 1and 1" pressed against each other. Said rolls 1' and 1 are respectivelymade by applying coatings 3 and 3' made of such soft elastic substanceas elastic rubber to the peripheral surfaces of roll bodies 2 and 2'made, for example, of a metal. 4 is an air-tight or liquidtight tubemade of such soft elastic substance as elastic rubber and, as clear inFIGURE 4, formed to be of a truncated tapered cross-section of which theperipheral edge 4 of the opening at the lower end is air-tightly orliquid-tightly fixed to the peripheral wall of each of a textile inletport 6 and outlet port 6 of a pressure-treating chamber 5 with a fixture7 and many screws 8 so that said tube may be inserted between both rolls1' and 1" mentioned'above. An air-tight or liquid-tight pressure chamber9 is formed at each end of each of the above mentioned textile inletport 6 and outlet port 6' and conend surfaces of both rolls 1' and 1"through a ring-shaped pressing fixture 11. Said air-tight orliquid-tight ring 10 is to be pressed against the end surfaces of bothrolls 1' and 1" also by the fluid pressure in the pressure-treatingchamber 5.

In the apparatus of the present invention, as shown in FIGURE 5, when atextile b to be treated is inserted between both rolls 1' and 1" of thefeeding roll device 1 and the rolls are rotated in the directionsindicated by the respective arrows, the textile b will be led into thepressure-treating chamber 5 through the textile inlet port 6, will beguided by many guide rolls 13, will thus advance Patented May 9, I967zigzag within the pressuretreating chamber 5 while being dyed, bleached,steamed or otherwise treated with a pressure fluid and will be let outof the pressure-treating chamher 5 through the textile outlet port 6after the completion of this treatment. When said textile b is led intoand out of the pressure-treating chamber 5, both side walls 4 and 4 ofthe above mentioned air-tight or liquidtight tube 4 of a truncatedtapered cross-section will be strongly pressed against the respectiveperipheral walls of both rolls 1' and 1" opposed to each other by thefluid pressure in the pressure-treating chamber '5 and at the same timeeach air-tight or liquid-tight ring 10 mentioned above will be pressedagainst the end surfaces of both rolls 1 and 1" by the fluid pressure insaid pressure-treating chamber 5 and pressure chamber 9 and theresiliency of the coiled spring 12 so that the above mentioned space aof a substantially triangular cross-section may be kept air-tight orliquid-tight at both ends. With these operations, the textile b will becontinuously led into and out of the pressure-treating chamber 5 throughthe textile inlet port 6 and outlet port 6, respectively, of thepressure-treating chamber 5 in a substantially perfectly air-tight orliquid-tight state.

In the present invention, with such simple construction and operations,textiles can be led into and out of the pressure-treating chamber in asubstantially perfectly air-tight or liquid-tight state. Therefore,textiles can be led into and out of the treating chamber withoutimpairing the air-tightness or liquid-tightness of thepressure-flu-id-treating chamber.

What is claimed is:

An apparatus for continuously leading textiles into and out of apressure-treating chamber comprising a feeding roll device comprisingtwo rolls pressed against each other and set in front of each of atextile inlet port and outlet port of a pressure-treating chamber, afluid-tight tube of a truncated tapered cross-section made of a softelastic substance and connected at the base end to each of the textileinlet port and outlet port, both side walls opposed to each other at thefree end of said fluid tight tube being pressed against the respectiveperipheral surfaces opposed to each other of both rolls of said feedingroll device by a fluid pressure in said pressure-treating chamber, and afluid-tight ring made of a soft elastic substance and set in a pressurechamber provided at each end of each of said textile inlet port andoutlet port and communicating with said pressure-treating chamber, saidring being pressed against the end surfaces of both rolls of saidfeeding roll device, so that a textile to be treated may be led into andout of said pressure-treating chamber through both rolls of each of saidfeeding roll devices, said fluid-tight tubes and said textile inlet portand outlet port.
